JPG to PPM Converter
PPM is the simplest image format there is — a short text header followed by raw RGB pixels. That’s why programming courses and image-processing projects use it. Convert any photo to PPM here.
JPG photos are placed in the PDF exactly as they are (no quality loss), so metadata such as the location stays inside the PDF. To remove it first, use Remove EXIF Data.
How to convert JPG to PPM
- Drop one or more JPG files into the box above — or click to choose them.
- Each file is converted to PPM straight away, right on your device.
- Download a single file, or all of them at once as a ZIP.
Why convert JPG to PPM?
- Binary P6 PPM that any PPM reader can parse in a few lines of code.
- Test your image-processing algorithms on real photos.
- Works with JPG, PNG, WebP, HEIC and other inputs.
When this conversion makes sense
Use this for programming exercises, image-processing experiments or command-line tools that read the simple PPM format.
Good to know
- PPM is a plain, uncompressed pixel format, so files are very large.
- Most photo apps cannot open PPM. Keep the JPG as your normal copy.

Frequently asked questions
What exactly is written to the file?
A binary P6 PPM: the header “P6”, a comment line, the width and height, the maximum value 255, then 3 bytes (R, G, B) per pixel, row by row from the top.
Why is the PPM file so large?
PPM is uncompressed: 3 bytes per pixel. Resize big photos first with the Image Resizer to keep files manageable.
What happens to transparency?
PPM has no transparency, so transparent areas become white.
Are my images uploaded to a server?
No. Conversion happens entirely in your browser on your own device. Your images are never sent to Imgovo or anyone else.
Can I convert several images at once?
Yes. Select or drop as many images as you like. They are converted one after another, and you can download each file or all of them together as a ZIP.
Can I undo a change?
Yes. Undo and Redo appear above the list once you add files (or press Ctrl+Z / Ctrl+Shift+Z). They bring back a file you removed, undo “Clear all” and return to the previous quality or format — files are converted again automatically when needed.
Is the converter free?
Yes — free, with no signup, no watermark and no daily limit.
